The iPhone passcode can still be bypassed after the iOS 6.1.3 update

It was just yesterday Apple released the iOS 6.1.3 update to address the lockscreen passcode bypass issue. Unfortunately, there is another work-around that will still give you access to the Phone app without entering the pass code.

To make this work though, all you need is a SIM ejecting tool or a paperclip. The good news is you can make your iPhone immune to this workaround by simply disabling voice dial in your passcode lock settings screen.
